Hop plant named ‘HBC 843’

Abstract

A new hop plant named ‘HBC 843’ is disclosed. ‘HBC 843’ is used for its exceptional and unique aromatic qualities, and is suitable for beer flavoring.

Description

Genus and species: Humulus lupulus.

Variety denomination: ‘HBC 843’.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

None

BACKGROUND OF THE INVENTION

‘HBC 843’ is a product of a controlled breeding program carried out by the inventors in the Yakima Valley of Washington State. ‘HBC 843’ was one of several seedlings resulting from a controlled cross made in 2012 with female parent ‘21055T’, an unpatented variety, and male parent ‘83-95’, also an unpatented variety. Seedling plants from this cross were planted in 2013 and screened for disease resistance and sex in a greenhouse and field nursery near Granger, Wash. A single plant of ‘HBC 843’ was selected in 2016. In 2016, ‘HBC 843’ was asexually reproduced via softwood cuttings, and expanded to 30 (thirty) plants in an evaluation block near Toppenish, Wash. In 2019, ‘HBC 843’ was further expanded to a one (1) acre test block near Moxee, Wash., with plants asexually reproduced via softwood cuttings produced from the evaluation block near Toppenish, Wash. The ‘HBC 843’ plants have now been observed and evaluated for several years. Throughout several generations of asexual propagation, ‘HBC 843’ has been observed to retain its distinctive characteristics and remain true to type.

SUMMARY OF THE INVENTION

A new and distinct hop plant is described herein, with the ‘HBC 843’ cultivar characterized by having cones with a high alpha acid content. The new cultivar exhibits cedar, lemon, honey, mango, orange, and rose aromas. The new cultivar is suitable for beer flavoring.

COMPARISON OF ‘HBC 843’ TO PARENT PLANTS AND COMPARISON CULTIVAR

‘HBC 843’ is distinguishable from its male parent ‘83-95’ with flowers that develop into mature hop cones without producing pollen, while flowers of ‘83-95’ produce pollen without developing into mature hop cones.

Table 1. below, sets forth some of the distinguishing characteristics of ‘HBC 843’ as compared to its female parent ‘21055T’, and to ‘Chinook’, an unpatented variety, as a closely comparable cultivar.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The ‘HBC 843’ hop plant is illustrated in the accompanying photographs, which show the plant's overall plant shape, leaf shape and cone shape plants nearing maturity at approximately four months of growth from the perennial rhizome.

FIG. 1 illustrates a maturing ‘HBC 843’ hop plant as growing on a trellis;

FIG. 2 illustrates a multiple of trellis with maturing ‘HBC 843’ hop plants;

FIG. 3 illustrates bines of a mature ‘HBC 843’ hop plant as grown on a trellis;

FIG. 4 illustrates whole mature cones and two male inflorescences (presumed sterile) of a ‘HBC 843’ hop plant; and

FIG. 5 illustrates cross sections of mature cones of a ‘HBC 843’ hop plant.

The colors of these illustrations may vary with lighting conditions and, therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from these illustrations alone.

DETAILED BOTANICAL DESCRIPTION

The following description is based on observations made in the 2020 growing season, of plants nearing maturity plant at approximately four months of growth from the perennial rhizome, at the test block near Moxee, Wash. It should be understood that the characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and can vary with location and season. Quantified measurements are expressed as an average of measurements taken from a number of individual plants of the new variety. The measurements of any individual plant or any group of plants, of the new variety may vary from the stated average. Color code designations are by reference to The R.H.S. Colour Chart, 4th ed., Copyright 2001, published by The Royal Horticultural Society of Great Britain.

• Ploidy: Triploid.
• Sex: Female.
• Use: Brewing beer and ale.
• Plant shape: Climbing bine, columnar growth, on typically 17 ft to 18 ft trellis height.
• Yield: Average yield is expected to be approx. 2,500 to 2,700 pounds per acre.
• Observed disease/pest resistance/susceptibility: Resistant to powdery mildew.
• Harvest date: Typically harvested September 18 to September 25, but can deviate from this time period, depending on growing practices and location.
